HOW TO MEASURE
For the best fit, measure your feet at the end of the day when they’re slightly larger.
- Place your foot on a sheet of paper against the wall, with your heel touching the edge.
- Mark the point of your longest toe and the point of your heel.
- I measured the distance between the two marks in centimeters. I did the same with the other foot.
- Enter the larger of your two foot sizes under “Find My Size.”
